Diva Carey appeared on Watch What Happens Live with Andy Cohen on Tuesday night and couldn’t resist throwing serious shade at Jennifer Lopez and Nicki Minaj. Mariah, who’s now in a habit of regularly dissing J-Lo, once again announced that she “doesn’t know who” her fellow singer is.

“If I had never had a conversation with you and someone asked me about you I’d be like, ‘I don’t know him but he seems cool’ or ‘I don’t know him’."

" Does she seem cool?" Cohen then pressed.

I don’t know her,” “What am I supposed to say? I’m not going to put on a thing like ‘Oh we're all Hollywood and let’s all pretend we’re best friends’ because we're in that land.

"It’s no offence to anybody. The question was about Beyonce and I said she was super talented, she's a friend of mine, she's always been sweet to me, and then they asked me another question and I don't know how I said it but I said, 'I don't know her.'"

The singer also took a swipe at rapper Nicki Minaj who she famously clashed with when they both appeared as judges on American Idol.

Cohen asked: “Can you say three nice things about Nicki Minaj?”

Mariah just stared blankly back.

“Can you ?” she replied.

“Sure.”

“OK, go ahead,” Mariah said as she turned her attention to her drink. “It’s your question."
